Boey's works have also appeared in anthologies like From Boys to Men: A Literary Anthology of National Service in Singapore, Rhythms: A Singaporean Millennial Anthology of Poetry and No Other City: The Ethos Anthology of Urban Poetry.
Boey's works are highly regarded by both the academic and writing communities in Singapore. Writer Shirley Lim remarked that he is the "best post-1965 English language poet in the Republic today". His own sense of restlessness about life in Singapore is reflected prevalently in his poems. According to him, Singapore's rapid growth and swift economic success are achieved at a cost. Feelings of displacement and disconnection with the past occurred precisely because places where one experienced his or her sense of belonging, through their childhood are fast disappearing.
